Does anyone know this?? 1. Why do we need to use the mole to count atoms? (2pts) 

 
2. What is the Molar mass of the following? Show your work
  a. H2O2  (4pts) 
   b. C2H6  (4pts) 

The answer is c if i’m not wrong

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.

The correct answer is "atomic weight".

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
